My invention relates to new and useful improvements in side bearings for freight cars, and has for an Aobject ,to providea bearing comprising a housing with self-een tering and interlocking rollers. Oftentimes the length of the rhousing must be limited and `by utilizingrthe arrangement aboutto be described, the length of thelionsing may bel-rept to a. minimum.

VStill another object of the invention is to provide a side bearing. comprising a housing in which' there `are two selfceiiter1ng rollers having portions Which overlap and interlock at times, butin no. Way interiere iiaees removed, and eachpoi' said rollers bef ing cored onthe oppositeside of the center of gravity from theent-away portion sor that, center when the loadis re-4 the roller will moved. i

irovide a; side benrnfr wherein therollers l s have :r part of their outer tace removed andj the opposite side cored, so that they .,iwiillk, center, to. provide further, `twogsmall ridgesr in the base ot' the housing Ywhich cooperate withcertain surfaces of therrollento: pred. vent theroller from tilting laterally4 `Within the housing when the load is removed from`v the rollers.V

Referring noyv more particularly `to the several vieWs,;I .have shown a box-like housing l-havingthe. slightly elevated bottom 2, while the hase is provided at eachv endi With the holes 3V for the-reception of bolts for .fastening thehousing to the truck or body bolster. The bottom elevated Wally 2 `is provided with .acentral longitudinal rib `4, 4to strengthen'r the same, and `prevent it f from sagging,'fand likexvisea rib 5 is shown ext-,ending` alongi the baseer' the housing and` `at each side of the `center rib, so that three ribs support the n housing` ,and

distinct rollers.

The housing -also has the Lflanges 6 kalon g its ,upper Yedge. and rthese flanges merge with the spaced langes ateach end of the housing,there heilig an open space 8 at the opposite'ends of thev housing as maylbeseen du. Figel endiy Y y As maybe seen in Fig. 2, tivo openings 9 occur, in eachfside of. the housing near: the

centerand"justabove the bottom Wall 2 sotliatliffany dirt ortoreignmatter gets into perspective of one .of therolll .the .boit-like,l housing, it may Work out through these openings 9,foi1ned in the op- 'i .posite sides of theliousino'.r` Oiievof the side `Wallsjfofthe "housing isy provided lWiththe' tWo ft-raks or y guidewaysd() i for the jV roller f trunnions, shortly tobe described, ,formed the ribell, andthe opposite side Wall 'l of the `housing is ,provided Jw'vith .similari ygnidevvays,i12 ytovrniedby`v the, ribs l13, but in this4 instance, fthe' guidewaysextend in aV direetionwoypposite to the guidewaysv 10.

Formed on ythe upper. surface of `the botfgtoinQ are kthe twozlaterally extending lugsv it will be seen that the housing is providedv with a raised bottom wall on which the roll-v ers will bear, and which in turn is strengthu ened by a plurality of ribs. Furthermore the end walls have openings therein, and the side walls are also provided with openings, so that any dirt may work out of the housing. The inner surfaces of the side wall are provided with ribs which 'forni guideways for thetrunnions of the roller bearings, and two transverse lugs are provided on the upper surface of the bottom wallV for steadying the rollers.

'Referring now more particularly to the rollers 16, it might be mentioned that one is a counterpart of the other, so that a, description of the one will suiiice.

The roller in its general outline is of 'the well known Vi/Tinety'pe,"having the rounded apex 17, the base 18 struck on a vlarger arc than the apex, and the flat faces 19 which merge with the ares of the apex and base. On the opposite sides of the roller are shown the trunnions Q0 adapted to fit within the guideways 10 and 12.

So that the rollers will not interfere with eachother when housed in such a relatively short space, and so thatthere will be an in- -gil terlocking action between the two rollers, when the rollers are at their either extreme of travel, I cut a portion off of the rolle-r starting near the top of one of the flat sides 19 andA about centrally of the length, this cutout portion thus being the deepest at the point 21, while at 22 the'cutout portion is slightlyc'oncaved, as may be seen in the several views, and this concavity bears and locks against, the bottom of the preceding roller as maybe seen at the' point 23 when the rollers are at their extreme limit of travel' (Fig. il).

lt isto be remembered that each 'roller is of the same `outline and shape, but they are oppositely Ydisposed within the housing so,

- thesides of theirollers overlap at their adjacent edges as shown in the dotted lines, Fig. 2. i'

froni'one of the faces of the same, the roller would beheavier on oneside thanthe other and wouldnot be self-centering unless somer` metal is removed from the other side Vof the roller to counterhalance ther lightened side. I, therefore, form a core 24 inthe roller, as maybe clearly seen in Fig. 4, the Vcore being` Referringagain to the rollers, it will be,V understood by glancing atFig. 8, that inasn'iuch as a part of the metal is removed diametrically opposite the ligliteiied side, thus permitting it to center itself when there is no load on the roller.

The rollers are placed in the housing bv inserting trunnions in the oppositely arranged guideways and turning the rollers slightly as they are inserted, so that the saine will come to rest on the iioor of the housing.

They will then appear as shown in Figs. 1, 2 and et, having their edges at one side overlapping. This miei-lapping in itself makes it possible to use a. shorter housing than would otherwise be the case.

The rollers are not free to rock or shift in either direction and iii Fig. 4.- I have shown them as shifting to the left, and when they reach their limit of travel, they will interlock and rest against each other, the concave portion of oneY roller bearing against the bottom arc of the preceding roller (see dot and dash lines).

rh'e lugs 14 and 15 ontlie opposite sides of the housing contact with the respective cut away walls of the rollers and thus steady the rollers. As the rollers revolve, the lugs willstill bear against the faces ofthe rollers, but there is no great load on the lug as the cut out portion widens as it extends toward the center of the roller, and iii this manner permits the roller to contact with the lugs and at the same time the load will be direct ed to the bottom plate ofthe housing.

The rollers will be tightly interloeked at either end of their travel and will remain this way until the curve in the track has been passed, after which the rollers` will unlock and self-center themselyes.

From the foregoing it will be seen that l have provided a heavy duty side bearing wherein two self-centering, interlocking rollers are used which may be positioned in a housing of minimum length. The rollers areV counterparts, but oppositcly'disposed, and although a. portion of the face of each roller is removed, it is properly countcrbalanced by coring a pocket opposite to the side which has apart of its face removed. `Means are also provided for a bearing against the cutaway face of the roller, to prevent the roller from tilting cndwise within the housing. Lastly, a great amount of frictional surface is obtained in a housing of relatively short length. i

Many slight changes might be made without in any waydeparting from the -spirit and scope of the invention.

Having thus described vmy invention, what I claim as new and desirevto secure by Letters Patent is LA side bearing comprising a housing7 self-centering non-tapering rollers "within" said housing, said rollers *provided with overlapping portions on their peripheral faces and said rollers capable of interlock-L 'ing when at tlieiieither extremity of travel.

Utl

'lofi 2. A side bearing comprising a housing, self-centering rollers within said housing, each of said rollers having a portion removed from itsl peripheral surface, the rollers being identical and oppositely disposed and intermeshing, and said rollers travelling in a straight path and capable of Y, an interlocking relation when attheir either extreme limit of travel. 8. A side bearing comprising a housing, two cylindrical rollers of the self-centering type, each of said rollers having a portion removed from its peripheral surface, said cutaway portion extending approximately one-half of the length of the roller, a portion of the roller having a' concaved surface .near its apex adapted to interlock with a portion. of the preceding roller when the said rollers have reached their extreme limit of travel within the casing.

4,-. A side bearing comprising a cylindrical roller vof the self-centering type, having a portion of one of its outer peripheral faces removed, and said roller being internally cored opposite the lightened face to thereby counterbalance the roller.

5. A cyliiidricalroller for a side bearing ofthe self-centering type having a portion removed from its outer peripheral faces, the

. f ont away portion extendingapproximately half the length of the roller and from a point near the apex to a point near the base,

and the bottom wall formed by the cut out portion being slightly concaved near its apex.

6. A roller for a side bearing of the selfcentering type having the apex 17, base 18, the iiat sides 19, the trunnioiis 20, the cut away portion 21, the concaveportion 22 and the cored portion 24. n i' 7. A side bearing comprising a housing, two cylindrical self-centering rollers Within the housing and each of said rollers having a portion of its circumferential face re'- moved to leave a convex surface and the rollers being transposed with relation to cach other so that the protruding and respective out away portions overlap and 1ntermesh when in their normal position, and

the said rollers being so housedthat they ture.

are contacting and interlocking when they reach either of their extremities of travel within the housing.

8. A side bearing comprising a housing,

box-like in cross section, the sides having openings formed therein, ribs arranged in opposite directions along the opposite sides to form guideways, self-centerin rollers having trunnions fitting within said guidecach extending from an opposite side to-V wards the center, rollers of the self-centeiing type having a portion of their faces removed, said rollers oppositely arranged so that the adjacent edges overlap, the said.

transversely extending lugs bearing against certain portions of the rollers to thereby prevent ythe rollers from tilting late-rally within the housing.

10. A side bearing comprising a housing `having a raised ybottom wall, ribs on said bottom wall for supporting the housing, ribs also formed on the inner surfaces of the side walls of the housing to provide a path for the trunnions of rollers, rollers within the" housing having trunnions` operating in said vguidevvays, said rollers being of the selfcentering type and each having a portion of one of'fits sides removed, vthe said rollers each being cored opposite said out awayv portion tov counterbalaiice said rollers, ineans formed in the. bottom wall of the housing for cooperatinggwith the cut away portion to preventr ythe 'rollers from tilting 5 laterally Within said housing.
